We have to use science to discuss these matters not common sense.
We should definitely use science to discuss this, but also common sense, because the belief in "gender identity" is strongly derived from a framework of functional illiteracy... Everything can be understood with basic common sense, if you take that out of the equation, you are left with abstract theories that may completely contradict observable reality and you lose the foundational baseline needed to define objective truth in the first place.
Common sense is not just some random "cultural bias" or something, it is the practical recognition of objective material reality...
The Hellenistic grammarians used originally "gender" to define classes and kinds, this was later used to classify people, but it wasn't until the 20th century, over 2000 years later that this term was used to create identities, which is a massive conceptual leap, this never began with any scientific discoveries or anything of that nature, it began with a subtle language change, later becoming institutionalized to be then transformed in a whole ontology.
If you believe that gender identity is more real than biological sex, then you are subverting the conceptual hierarchy. Gender depends on sex, not the other way around. "Male" and "female" only have meaning if they are connected to the original biological differentiation between the sexes.
If sex is removed as the grounding reference point, what exactly anchors the concepts of "male" and "female"? Without that foundation, what do those terms even refer to?
Judith Butler was one of the first to argue that gender is not something a person "is" but rather something that a person "does". According to this theory gender is a series of repeated actions, behaviors, and roles that are socially conditioned from birth. In this framework, "masculinity" and "femininity" do not exist as scientific, biological realities, but as societal scripts. Now, this influenced the modern science and the so called discoveries that are in fact pseudo-science. Also note, Judith Butler is a jew, as could be expected. This entire narrative is created, pushed and promoted by the jews.
Butler's ontological framework does not make sense in the real world. She not only argues that gender is not merely something society develops, but also that it is what constitutes the subject itself. Which means biological sex ceases to be understood as natural data with intrinsic meaning and is instead treated as an effect of discourse, this is a dangerous line of thought because now, gender is presented simultaneously as a social construction and as the foundation of being. Which means the subject fully exists only when socially recognized. Which in other words means that external recognition assumes ontological primacy.
This translates to the subject being produced by social norms, which in turn exist only because they produce subjects. No one exists prior to recognition, yet no one can recognize without already existing. Reality seems to disappear in a circular loop. But who cares about reality anyway, right?
Simone de Beauvoir a jewish philosopher laid the groundwork for modern feminist theories which introduced the idea that "femininity" was a social construct and not something related to biology, saying you're not born a woman but become a woman.
Robert Jesse Stoller was a jewish psychiatrist that along with John Money were the major influences in introducing the medical distinction between "sex" (biological) and "gender identity" (psychological), the pretext was clinical but the background intention was to show that male and female behaviors would be in large part socially constructed and therefore moldable
The jewish examples are many. You can do your own research, these are just a few to tell you that they are the ones pushing this entire narrative to normalize degeneration among Gentiles.
I will never allow anyone to call me mentally ill and disrespect me
There is no reason to disrespect you and I am not saying these things to attack you. But I am sorry to tell you that it wasn't until 2019 that you stopped being officially considered mentally ill. In 2019, the World Health Organization moved "gender dysphoria" out of the mental illness category. This did not happen because of any major scientific breakthrough it was a conceptual reframing related to human rights.
There was no new biological mechanism suddenly discovered that revealed gender identity to be a measurable physiological condition. Scientifically speaking, there were no new discoveries proving that gender identity overrides biological sex.
